Hi there, time to share ways to keep your home cool during hot times
So ok, usual ways I use:
- open everything during night
- close everything during day
- external sheets on windows without shutters
- some curtains to prevent heat from going upstairs
I was also wondering if plants could also help inside, any ideas ?
Share your advices !
Offices in all countries have AC, the question is about homes. I doubt “practically every household” in Hokkaido has AC. Here in northern Europe, very few do.
My office in Southern Germany doesn’t have AC, even though it should. It’s the hottest part of Germany.
Give it a couple of years and a few more heatwaves! This is the insidious problem with heatwaves, as I see it. Tolerance for heat and cold is in large part cultural - go to Portugal in winter to see how tolerant people can be of cold indoor temperatures. But with every new 3-day heatwave, Europeans are going to rush out to buy AC units to escape the immediate misery. Next thing we know the continent will be like the US, where it’s just unacceptable for indoor temperature to be outside the 19-23C range. And mass AC is just a climate disaster. That’s my worry.
Every home I have visited in Japan over the past two decades has had A/C units. You may be right that in regions where it is very cold an A/C unit may not be necessary. However, as heat pumps are one of if not the most energy efficient ways to not only cool but also heat a home, I wouldn’t be surprised to find them even in colder regions.
Add on the fact that houses in Japan are generally considered a depreciating asset, so until recently demolitions and new construction were favored over renovations, I stand by my first statement.
Additionally, every place I have ever rented has come with at least one A/C unit, and additional holes are predrilled in other rooms so that split systems can be installed.
Fair enough. Most of Japan is hotter in summer than northern Europe. Here it has been 35C for much of the last week and domestic AC penetration remains extremely low. There are also quite few fat people, and the two things are probably at least a little bit connected.
I don’t disagree that people who are overweight will feel hotter. The rainy season makes it feel hotter than just the temperature here, too. Buildings here are probably more poorly insulated, too.
